To all whom t may concern'.

Be it known that I, DANIEL E. ERICKSON, a citizen of the United States,and residing in Mamaroneck, in the county of Westchester and State ofNew York, have-invented certain new and useful Improvements inOil-BurningApparatus, of which the following is a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and Vuse the same. A

This invention relates to fuel-oil` burning apparatus, and moreparticularly to improvements in oil-burners especially adapted forsteam-boiler furnaces.

It is an object of the invention to provide an eicient and practicaloil-burner of the character mentioned.

Itis a further object to provide an improved apparatus whereby thefuel-oil is insured thorough volatilization'and the combastion isedected with a proper, and regulable volume of air. Another object is toprovide an apparatus for the purpose set forth which is capable of readyadjustment to operate at maximum eciency under dierent conditions, andis further capable of convenient assembly and dis-assembly whenrequired.

Broadlyit is the object of the invention to provide an improvedoil-burning apparatus having lfeatures of structural superiority andfunctlonal advantage. e,

Other objects and advantages vwill be noted hereinafter in connectionwith the following description of the accompanying drawings,which'illustrate a preferred embodim'ent o f the invention, andl whereinFigure lis a'central sectional view of the burner apparatus, taken onthe line 1--1 of Figure 2.

Fig. 7 is an end detail view of the deflector, exposing the baffle vanesthrough the air inlet, and

Fig. 8 is a side'sectional elevation of Fig. 7 taken on the line 6 6thereof.

Referring. more particularly to the drawings, there is represented apart of a furnace front 7 having a circularopeningS and an'r interiorcasting 9 secured thereto andA affording a conoidal chamber 10 thatexpands inwardly from the opening 8; The oil-- burning apparatuscomprises, in general, a unitary assenibl applied, and preferablyhinged, to the urnacafront concentric to' cylindrical and has an openouter end 14 save for spider arms 15 which join the same wlth amateriallysmaller circular eX- tremity 16 having y acentral' bore 17there'- through. rlhe inward' portion of casing 11 has the centeringinterior surface 111- for directing the flow of air centrally toward.

thel furnace entrance. The casing end 16 constitutes the sup ort for atube 1 8 extending through bore 1 and projecting inwardly to about theplane of the opening 8 in the furnace front. Tube 18 in turn is held bya set-screw 19 and its outer end is'threaded to receive a hollow nut 20which releasably holds a block 21 with a conduit 22 connecting the fuelsupply pipe' 23 and the discharge pipe 24.- The lattervis supported by`block 21 and, extending axially within tube 18, is provided withl aterminal burner tip volatilization of the oil, supplled preferablypreheatedand under pressure.

25. The burner tip/ is of character to effect" At the inner end of tube18, there dis also provided a surrounding flared element 2'6 which islongitudinally positionable and 'l 4functions-as an air delector andlame cone.

This element, in the construction shown, has' attached theretoa pair ofrods 27 extending parallel to the tube 18 and outwardthroughcasingextremity'l to terminate in ing a central opening 31, at itssmaller end,.

and having an inturned flange 33 at its larger end to co-act with thefront surface 34 of an annulus 35, that is secured to the furnace frontby bolts 36, said element 30 being movable along the tube 18 as by asecond pair of rods 37 which protrude outwardly and terminate in handles38, whereby element 30 is capable of independent adjustment to controlthe volume and 'force of the draft of incoming air, whereby thecharacter ofthe combustible mixture may be governed.

The conoidal element 30, which, it will be noted, opposes its base orlarger extent to the furnace opening. 8, thereby constitutes a chamberfor pre-heating the air supply that enters at the orifice 31. The flange33, which is in the form of an annular inturned lip, presents its outersurface'33a in opposition to the outer surface portion 34 of annulus 35,at acentering angle, said surfaces 33a and 34 being in substantiallyconcentric parallelism, to thereby accord a centering or conoidalformation to the volume of air flowing into the furnace from casing 11.It will of course be appreciated that the volume of air thus introduced,as well as its speed of travel, are regulable by the transverse extentof the passage between surfaces 33"l and 34, said extent beingadjustable through the axial movement of member 30.

The conoidal member 30 is slidably mounted on tube 18 by a collar 30a,vwhich connects with memloer-v 30 by radial or spider arms 30". vAlsocarried by collar 30*1 is a series yof radial, angularly disposed vanes30, that ex-l tend transversely between the opening- 31v in member 43 0and the furnace opening, thus serving 'the vtwofoldlpurpose of causingair that passes to the furnace through opening 31 to have a whirlingmotion, and also comprising a baffle which prevents the direct radiationof furnace heat out through opening 31. In effect heat is by this meansconserved within member 30, which thus becomes apre-heating chamber for-the air supply that enters through opening 31, thereby enhancing itscombustion'supporting efficiency. The air deflectin-g element 26 whichsurrounds the burner tip may be provided with openings,.here shown inthe form of slots 41, to permit some of the preheated air from member30. to enter within the conoidal chamber of element 26, tothus aid 'inthe support of combustion near the ame genesis, where the -burner tip issupplied with air by supply entering through tube 18.

The. technical effect achieved in improved combustion b thusintermingling the air y annulus at its entrance, 1n combination, a

supplies 'in the region of flame generation is important, and, Ibelieve, new with me'in the art.

Block 21 has a handle 39 and may be convenient-ly mounted by a screw 40so that the block and pipe 24 and burner tip 25 can be withdrawn readilyand as a unit'when desired for any purpose. l

In operation oil is projected into the combustion chamber through theburner tip 25 and in a finely divided state forming a combustiblemixture with air which enters through tube 18, vthrough casing 11,around and through conoidal` member 30, and through the slots in member26. The adjustment of said member 30, and the independent adjustment ofthe member 26, as described, enables a regulation and fine control ofthe course of incoming air and thereby the relative proportions of airand oil in the combustible mixture as well as the shape and length, toan extent, of the burning flame. withdrawn its full length from thefurnace it closes the air intake to casing 11, and constitutes a doorshutting off the passage of air to the furnace.

It will thus be observed that the apparatus as described attains, amongothers, the objects and advantages before noted. It is to be understood,however, that the invention is capable of modification without departingfrom the intended scope of the following claims.

Having thus described my invention, what yI claim as new, and desire tosecure'by Letters Patent is: n
